Florida man accused of killing pregnant ex with machete

Police say a pregnant woman was on the phone with a victim's advocate when a fight with her ex-boyfriend turned violent and he killed her with a machete, CBS 12 News is reporting.

Horacia Siemus had an active domestic violence case against her former boyfriend Youvens Madeus and she was prepared to testify against him.

Not wanting their dirty laundry to be aired in front of a court, Madeus came to Siemus' West Palm Beach home Monday to try to dissuade her from testifying.

The conversation turned into a fight and Siemus called the State Attorney's domestic violence office as she tried to get away. She was at the door when police say Madeus hit her with a machete, delivering a fatal blow.
